광산 폐석을 골재로 이용하는 콘크리트의 특성에 관한 실험적 연구(II) - 슈미트 햄머 및 초음파법 비파괴시험 ( An Experimental Study on the Properties of Concrete Using Mine Waste as Aggregate(2) )

To analyze the using of mine-waste as the substitude aggregate is important problem on the shortage of resorce aggregate. Continued from study I(the mechanical property analysis of mine-waste aggregate), this study is aimed for presenting the reference data to the practical use of quality control by the non-distructive testing on mine-waste concrete.
